DAMPER FOR GRATES.

SPECIFICATION forming part of Letters Eatent No. 599,335, dated February 22, 189 8.

Application filed April 1'7, 1897. Serial No. 632,658. (No model.)

To aZZ whom it may concern.-

Be it known that we, FREDERICK W. KEI- FEL, J r., residing at Louisville, Jefferson county, Kentucky, and JOHN ZIPP, residing at New Albany, Floyd county, Indiana, have invented certain new and useful Improvements in Dampers for Grates, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in open grates; and it has for its objects, among others, to provide an improved damper whereby the draft and the provision for the escape of the products of combustion can be perfectly adjusted or regulated, the main damper being provided with a supplemental register slide or damper adapted to be actuated with ease by means of a lever or other device, the construction being such that the sliding damper may be operated regardless of the position of the pivoted damper upon which it is mounted.

A further object of the invention is to provide a guide and guard for the operating-rod which actuates the pivoted damper and also to partially rotate said rod under certain conditions.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form part of this specification, and in which Figure 1 is an end elevation. Fig. 2 is an elevation looking at the opposite end. Fig. 3 is a plan of the pivoted damper and the sliding damper mounted thereon. Fig. 4 is a detail of the bar employed for holding the brickdeflector. Fig. 5 is a detail perspective of the brick-holding bar. Fig. 6 is a detail perspeotive of the end of the sliding damper and the operating-lever for the same. Fig. 7 is a similar view of the bracket carrying the rack detached from the grate. Fig. 8 is a similar view of the operating-lever for the grate, and Fig. 9 is a detail perspective for the damperoperating rod for the pivoted damper.

Like letters of reference indicate like parts throughout the several views.

Referring now to the details of the drawings by letter, A designates the grate, which may be of any well-known or approved form of construction, mounted to be reciprocated and rocked in the usual manner.

B is a lever pivotally mounted in any suitable manner and connected with the grate to reciprocate the same back and forth in the direction of its length. The forward end of this lever, which projects through a suitable slot in the front portion of the frame, is provided with an opening 0, in which is adapted to engage the bent end of the link (3, the other end of which is slotted, as at c, and in this slot is designed to he detachably engaged the hook cl on the operating-lever D, which may be of any suitable material or length and the lower end of which is adapted to be engaged in a socketd, secured on the front of the frame to form a bearing for the lower end of the lever. By this construction the hand is removed from the heat in operating the grate, and by means of the link connection ease of movement is secured.

G is the damper, pivotally mounted in suit able bearings at the upper end of the rear of the frame of the grate, and the shaft or pintle G thereof is extended at one end and receives the upper end of the curved arm G, which is held fast thereon in any suitable manner. This arm is formed with the outwardly-extending portion 9 at its free end and between its ends with the downwardly and inwardly curved lug g H is a bracket or arm secured to or integral with the end of the frame adjacent to the curved arm, and this bracket is formed with a plurality of rack-teeth or notches h upon its upper face and with the end plate H", which has an aperture to receive and guide the sliding rod I and with the guard H above and parallel with the rack-teeth h. This serves as a guard for the rod to prevent ill.- jury thereto and also to prevent its coming out of operative position. The rod I is mounted to slide through the opening in the front plate and at its outer end is provided with a handle or analogous means a, while the inner end of this sliding rod is formed with the inwardly-extending arm or projection 1, adapted to engage beneath the curved arm secured to the end of the damper-pintle, so as to raise the same and move the damper on its pivot, and at the same time serves to engage the teeth or notches of the rack on the bracket and hold the damper in any of its adjusted positions. The extreme inner end of this sliding rod is formed with an oppositely-extending arm or projection 1 which engages and travels beneath the guard H on the bracket, whereby it is limited in its rotary movement, and when the arm I is thrown out of engagement with the rack it engages this guard H to prevent the further rotation of the rod and is guided thereby when the rod is reciprocated.

The rod 1, which is mounted for both a sliding and rotary movement, has its head or handle z'provided with indicating means, such as the projections or studs 1' and t the former of which when in a vertical position indicates that the arm I is in a horizontal po sition to engage the rack, and when the projection t is in a vertical position it indicates that the arm I is in a vertical position out of engagement with the rack and in contact with the guard H It will be observed that when the rod I and the pivoted damper are not in use the former can be pushed inward flush with the face of the grate by turning the arm I away from the rack and passing it beyond the curved arm G. When the rod I is in its inmost position, the arm I thereon is beyond the convex face of the lever G, and if the rod be pulled outward it would strike against this arm. To prevent this, the curved lug g extends inward and downward, so that when the damper is closed it lies over the teeth of the rack. With this device when the arm I reaches the lug g in the outward movement of the rod the arm is thereby turned upward, so as to pass the convex face of the arm, and then again drops back into engagement with the rack. It will thus be seen that the lug turns the rod and its projecting arm, so that the same will pass the arm and can then be placed in proper position for the operation of lifting the damper by pushing the rod inward.

J is the fire-brick, arranged to the rear of and beneath the damper and occupying the place occupied by the lower damper heretofore provided in this class of grates. It rests at its lower edge upon the upper edge of the rear portion of the lining of the grate, and K is a cross-bar suitably supported upon the side walls and resting upon the upper edge of this brick. The bar is provided with lugs k, which extend over the upper edge of the brick and terminating in lugs K, that engage over the front face thereof to support the upper edge of the brick and permit its expansion and contraction. The lower edge of the damper is formed with recesses Z, which permit it to close over the arms of this cross-bar.

The upper and rear face of the pivoted damper is formed with guide-lugs M, between which is mounted to slide the supple-mental damper or register slide O,provided with a plurality of openings 0, which are designed to register with or close the openings 0 in the pivoted damper. It is often found desirable, if not necessary, to regulate the draft and the provision for the escape of the products of combustion more minutely than can be done by means of the pivoted damper alone. This sliding damper or register permits of the most minute and accurate adjustment, and provision is made for the manipulation thereof regardless of the position or inclination of the main pivoted damper. For this reason we provide the sliding damper with the lug or extension P at one side, which is curved forwardly into a line with the pivot of the damper G, as shown at p, and at its free end is provided with the lug P, having the head 19, which is engaged in the elongated slot q, formed in the upwardly-extending arm Q of the rocking-rod Q, mounted to work through an opening in the grate-front and to oscillate in an opening in the lug S cast upon or secured to the end of the grate. The outer end of this rocking-rod is provided with a handle or lever T, by means of which it may be rocked, and by manipulation of which the sliding damper or register may be operated independent of the position of the pivoted damper, as the point of connection with the rod is in line with the pivotal point of the damper G.

The features hereinbefore described may be used separately or collectively, and one or more of them may be present in the same grate, or anyone of said features will serve in connection with a grate having the other portions thereof constructed differently from what has been hereinbefore set forth.

It is obvious that changes may be made in the details of construction and configuration of the several parts without departing from the spirit of this invention as defined by the appended claims.

Having described our invention and set forth its merits, what we claim as new, and desire to secure by Letters Patent, is

1. The combination with a pivoted damper and means for operating the same, of a sliding damper mounted to slide upon the pivoted damper, a pivoted operating-rod, and a connection between said operating-rod and the sliding damper whereby the latter is adapted to be operated at whatever position it may be carried by the pivoted damper, substantially as specified.

2. The combination with a pivoted damper and means for operating the same, of a sliding damper mounted to slide upon the pivoted damper, a forwardly-extending arm located on said sliding damper, a pivoted operating-rod, and a slotted connecting-arm extending from said rod and engaging the arm on said sliding damper,substantially as speci- 3. The combination with a damper and an arm for operating the same, of a rack-bar, an operating-rod to engage said arm and having arm and extending downwardly to one side thereof, a rack-bar adjacent to said lug, a reciprocating and rotating operating-rod to actuate said arm, and a projection on said arm to engage said rack and adapted to be partially rotated by engagement with said lug, substantially as specified.

In testimony whereof We aflix our signatures in presence of two Witnesses.
